How likely is my planning application to get approved in Havering?

Asking whether your planning application will get approved in Havering is a bit like asking whether your car will pass its MOT — the answer depends entirely on what's under the bonnet. The borough covers a huge range of property types, designations, and constraints, and two houses on the same street can face completely different planning rules. Tools like WhatCanIBuild exist precisely because that complexity is almost impossible to unpick without looking at your specific address.

Havering isn't one planning area — it's many

Most homeowners think of Havering as a single place with a single set of rules. It isn't. The borough has substantial Green Belt land covering much of the north and east, which imposes restrictions that go well beyond the standard planning framework. Properties in those areas face a fundamentally different set of considerations to homes in Romford or Hornchurch.

Then there are conservation areas, listed buildings, flood zones, and Article 4 directions — each one capable of overriding the rules you thought applied to your project. Most homeowners don't realise these designations exist until they're already mid-application, and by then the damage is done.

Your postcode is only the starting point

Havering postcodes run from RM1 through to RM14, and the planning picture shifts considerably across that range. But even within a single postcode, individual streets — sometimes individual properties — sit inside or outside designations that change everything.

A rear extension that sailed through planning on one side of a road might have been refused on the other. That's not a quirk — it's how the system works. The designation boundaries don't follow streets. They follow maps that most homeowners have never seen.

The decision time for a standard householder application in Havering is around 8 weeks, and the application fee is £258. But submitting an application that was always likely to fail is an expensive way to find out your property has constraints you weren't aware of.

What similar applications nearby actually tell you

Here's where it gets genuinely complicated. Even if you know your property's designations, knowing what to make of them is a different question entirely. Being in a conservation area doesn't tell you what that means for a loft conversion on your specific house. Knowing your neighbour got permission for a side return doesn't mean you will too — their application might have succeeded despite a constraint your property also has, or because of a difference in plot layout you haven't accounted for.

The best way to understand your actual approval odds is to look at what's been approved and refused for similar project types on similar properties nearby — and understand why those decisions went the way they did. That's the gap WhatCanIBuild closes: not just what constraints exist on your property, but what they've actually meant for applications like yours.

Before you spend £258 finding out the hard way

The stakes of getting this wrong aren't abstract. A refused application sits on the public record. It can complicate future applications on the same property. And the fee is non-refundable.

Most homeowners submit applications without a clear picture of how their property's specific combination of constraints has affected similar projects nearby. WhatCanIBuild gives you that picture before you commit — so you're not guessing.
